Clutch device for a hybrid drive system

Abstract

A clutch device that includes a first and a second input side, a first and a second output side, wherein the input sides and the output sides can be rotated about a common rotation axis. The clutch device further includes a first clutch between the first input side and the first output side, a second clutch between the first input side and the second output side, a third clutch between the first input side and the second input side, and an actuator device for the third clutch when the second input side rotates faster than the first input side.

The invention claimed is:

 a second clutch disposed between the first input member and the second output member; 
 a third clutch disposed between the first input member and the second input member; and 
 an actuator device for the third clutch when the second input member rotates faster than the first input member, wherein the actuator device includes a first axial end directly connected to the first input member and an opposing second axial end directly connected to a third clutch output member. 
 
     
     
       2. The clutch device of  claim 1 , wherein the actuator device comprises a passive actuator device configured to transmit torque only from the second input member to the first input member, but not an opposite direction. 
     
     
       3. The clutch device of  claim 2 , wherein the passive actuator device comprises a leaf spring element that is inclined relative to a rotational plane about the common rotation axis, and axial ends of the leaf spring element are in contact with the first input member or the second input member. 
     
     
       4. The clutch device of  claim 1 , wherein the first input member is configured to receive an axial actuating force from the first, second, or third clutch. 
     
     
       5. The clutch device of  claim 1 , wherein the actuator device is arranged radially inside the third clutch. 
     
     
       6. The clutch device of  claim 1 , wherein the first and second clutches are radially offset and configured to be actuated from the same axial side. 
     
     
       7. The clutch device of  claim 1 , wherein the first input member is held relative to the common rotation axis by using a radially inwardly extended holding element. 
     
     
       8. The clutch device of  claim 1 , wherein the first, second, and third clutches are arranged in a common housing which is partially filled with a liquid medium. 
     
     
       9. The clutch device of  claim 1 , wherein the first input member is configured for connection to a rotor of an electrical machine. 
     
     
       10. The clutch device of  claim 9 , wherein the rotor is surrounded radially outwardly by a stator of the electrical machine. 
     
     
       11. The clutch device of  claim 1 , wherein the second input member is configured for connection to an output shaft of an internal combustion engine. 
     
     
       12. The clutch device of  claim 11 , wherein the third clutch is disposed between the first input member and the second input member and an actuator device for the third clutch is provided when the second input member rotates faster than the first input member. 
     
     
       13. The clutch device of  claim 12 , wherein the actuator device includes a passive actuator device configured to transmit torque from the second input member to the first input member, but not an opposite direction. 
     
     
       14. The clutch device of  claim 13 , wherein the passive actuator device includes a leaf spring element configured to exert an axial actuating force on the third clutch when the overrun device transmits torque between the second and the first input members. 
     
     
       15. A clutch device comprising:
 a first and a second input member; 
 a first and a second output member; 
 wherein the input members and the output members can be rotated about a common rotation axis; 
 a first clutch disposed between the first input member and the first output member; 
 a second clutch disposed between the first input member and the second output member; and 
 a third clutch disposed between the first input member and the second input member; 
 wherein the first input member is configured to form an axial contact for friction linings of the first clutch and for friction linings of the third clutch; and 
 a leaf spring of the third clutch, wherein the leaf spring includes a first axial end directly connected to the first input member and an opposing second axial end directly connected to a third clutch output member. 
 
     
     
       16. The clutch device of  claim 15 , wherein the leaf spring extends tangentially to a periphery around the rotation axis or helically on the periphery. 
     
     
       17. The clutch device of  claim 15 , wherein the first axial end of the leaf spring is connected by friction engagement or fixedly to the first input member. 
     
     
       18. The clutch device of  claim 15 , wherein the leaf spring is radially towards the rotation axis with the respect to the third clutch.
